Advanced Audio Coding (AAC) is a digital audio file format that reduces file size via lossy compression. Its primary uses are digital TV, digital radio, and Internet streaming. It is the standard audio format for iOS, YouTube, Nintendo, and Playstation. ISO/IEC designated the AAC codec as an improvement to MP3, due its ability to compress file size more efficiently while providing quality similar to uncompressed audio.

 

How to open an AAC file?

For best results, use VLC media player to open AAC files. Alternatively, AAC also opens by default in iTunes. AAC files are ubiquitous, however, and open in many other programs and software.

 

Additionally, since AAC files often serve as the audio files for video games, they open on most popular gaming consoles, such as Nintendo 3DS and Playstation 4.

Flash Live Video (FLV) is, as the name suggests, a type of Flash video. It is a popular format that delivers high-quality, well-synchronized multimedia content, primarily over the Internet. It is also a media container, and as such, uses codecs to compress file size. FLV uses the open standard ISO/IEC 14496-12:2008, also known as the ISO base media file format, which offers the advantage of flexibility and independence.

 

How to open an FLV file?

By default, FLV opens in Adobe products, namely Animate Creative Cloud (Animate CC) and Flash. It opens best in Adobe Flash version 7 and above. FLV does not support chapters or subtitles, but it does support metadata tags.

 

Since FLV is based on an open standard, it can open in many non-Adobe products. Other programs in which FLV can open include VLC media player, Zoom Player, RealNetworks RealPlayer Cloud, Eltima Elmedia Player, and others.
